|Summary:||Physical separation processes constitute a cost-effective approach to remediate contaminated sediments. A laboratory-scale physical separation process using froth flotation, Wilfley table (WT), and physical separation column (PSC) as the key unit operations was studied using Sandy Beach sediments (Gaspé, Canada) contaminated with metals, mainly copper (Cu), and polycyclic aromatic hydrocarbons (PAHs). Copper was distributed (89-96%) mainly in the fractions ???? 2 mm) were more effective for PAH removal than Cu removal. Overall, the treatment process resulted in a cleaned sediment recovery of 74-75% (w/w) with the following pollutants removed: 71-80% PAHs, 61-65% Cu, 27-33% Zn, and 36-40% Pb.|
